| Abstract: | An experiment was performed to remove iron ions from leach solution of low-grade copper oxide ore by hematite precipitation process. The results show that the iron removal rate is 95.2% and the contents of iron, copper and sulfur in the residue are 62.7%, 0.14% and 1.6%, respectively, under the optimal processing conditions for iron removal, including reaction temperature of 180 ℃, an initial sulfuric acid concentration of 2 g/L, reaction time of 3 h, partial pressure of oxygen at 0.3 MPa and stirring speed at 400 r/min. |
